Please try mono from svn. There are several improvements in the GC
code and xsp should behave much better. For example, I just finished
a run of 25000 requests at a web service hosted with xsp that involve
a few tens of KB of data for each request and xsp's memory
usage is constant at 31 MB (virtual, 16 MB RSS).
So, please try mono from current svn and file a bug report with a test
case if you still see the memory usage increasing.
